Radio frequency spectroscopy has been carried out on molecular beams of chloroacetylene to yield Stark and chlorine hyperfine properties for the ground and excited C--H stretching vibrational states. For HCC/sup 35/Cl v = 0, ..mu.. = 0.440 079(1) D, eQq = -79 733.59(4) kHz, and C/sub Cl/ = 1.412(4) kHz. For HCC/sup 35/Cl v = 1, ..mu.. = 0.462 792(1) D, eQq = -79 744.59(5) kHz, and C/sub Cl/ = 1.398(3) kHz. For HCC/sup 37/Cl v = 0, ..mu.. = 0.439 954(1) D, eQq = -62 839.68(9) kHz, and C/sub Cl/ = 1.142(6) kHz. For HCC/sup 37/Cl v = 1, ..mu.. = 0.462 778(1) D, eQq = -62 848.64(10) kHz, and C/sub Cl/ = 1.127(8) kHz. The above results are for J = 1 levels, while J = 1 and J = 2 Stark data for the ground state were combined to give an electric polarizability anisotropy, ..cap alpha../sub parallel/--..cap alpha../sub perpendicular/ = 3.87(2) A/sup 3/.
